Well, nobody except the >80% of the world's computer users.
Sheesh.

No, that's not true. 99% of that 80% are totally ignorant of what they have, why they have it, whether it's any good and the fact that it attracts all that spyware and virii like flypaper. They just use whatever was on their desktop when they got their computer.
So they sure as hell won't care.
The only people who will care are the diehards who actually prefer IE for whatever reason.
i.e. Bill Gates, Steve Ballmer and maybe their wives. That's it.
